I want to see a spinner bot use a viscous coupling on the weapon as a shock damper. That should dissipate the shock force instead of heavily stressing (and often breaking) the drive system. Such a coupling would need a lot of surface area and a filling material that stays stiff and sticky to be able to transfer power, yet can shear under a hard and sharp load so it'll slip. For high surface area in a small-ish space use multiple nested rings (deep concentric grooves cut into disc faces) or flat rings like an automatic transmission clutch pack or limited slip unit as used in many all wheel drive vehicles. In vehicles the viscous limited slip is filled with a thick silicone oil and transfers no or little power until the primary drive wheels slip. That causes a speed difference across the VLS. The shearing makes the oil heat and thicken. What's needed for a battle bot weapon (or wheel) drive that can slip to protect motors, belts, gears etc is a substance that's thick and grippy until there's a sharp shock. It needs to be able to shear and slip then quickly return to thick when the resistance is gone. My suggestion is a silicone grease. To make more area for the coupling filling to grip, drill holes through the rings, perpendicular to the faces of the flat rings, radially through the vertical concentric rings.
@JustCuzRobotics4 жыл бұрын
Sounds like you are describing a more or less standard clutch system which is already in use on many of the larger battlebots spinners and hammers. For the smaller bots the amount of stretch in a belt or slip from a belt on a smooth pulley is sufficient to prevent shock loads from damaging components.

Hi, greggv8! That's an intriguing idea, and definitely worth investigating. I'm in no way trying to be negative, but I can see a couple of possible problem areas: weight and complexity. In my limited experience [I'm not a qualified engineer, but I've been building and fighting heavyweight bots since 1987], if something can go wrong, it will. I think that's why things like tracks and walking mechanisms don't get used on combat bots very often. You do see some very clever stuff on military-style bomb-disposal robots, but they're not faced with weight restrictions and only have to deal with booby-traps and high explosives, not monster kinetic weaponry. ;-) Repairs to belts, sprockets and chains are reasonably quick and straightforward in the kind of 'table-top' service areas you get at many events; the sophisticated additional coupling you describe might need some pretty advanced servicing facilities. Like a garage, a hoist, and a guy in greasy overalls with a clipboard shaking his head about what the repair's going to cost. "You see, lady, the problem is, we just can't get the parts..." The weight of the unit itself might be an issue, but sound engineering could probably get around that. I've no doubt that a viscous coupling could be made sufficiently robust, because there's nothing much to break internally. (A rally car's 4-wheel drive system can take a lot of abuse.) It's just that today's bots are so powerful that when things like shrouds and housings get hit, they explode; and it's not uncommon to see an entire chassis bent out of shape. Flexible belts are light and will usually keep working after that kind of major impact; I'm not sure it'd be possible to keep a 'bent' viscous coupling running smoothly, and protecting it would mean surrounding it with a lot of fairly heavy/massive protection. I'd love to see someone working on the idea, though.
@EleanorPeterson4 жыл бұрын
@@JustCuzRobotics - Ah, right. Sorry. I was thinking in terms of something huge and complex fitted directly to the motor's output shaft. Direct drive, splines, keyways, um... yes. That would do away with the need for belts and pulleys and gearboxes and whatnot. Spin-up and stall-protection would be a case of clever electronics and custom ESCs and so on. But as I know next to nothing about electronics, this is where I bow out, blushing, and you step in, laughing at my idiocy...
@greggv84 жыл бұрын
@@EleanorPeterson Not so complex. For a horizontal disk like PP3D I'd use a shaft within a shaft. The outer shaft driven by the motor, the disk attached to the inner shaft, with a pair of car wheel bearings and races supporting it in the outer shaft. Might use a plain bushing and a thrust washer on the bottom because the inner shaft isn't going to be running at high RPM relative to the outer shaft. The viscous coupling I'd mount on top, with one grooved disk connected to the the outer shaft and the other held to the inner shaft with the same nut that holds the inner shaft. The bottom disk of the coupling would have an outer wall extending upward to keep the silicone grease inside. With a lid on it, grooved on its underside, the upper coupling disk would be the middle disk with grooves on both sides. I'd also use the silicone grease on the bearing and bushing on the inner shaft for more stickiness for getting the weapon disk moving. The design for mounting on a motor shaft or an intermediate shaft would be similar. Thus the coupling is inside the robot, inside the heavy/massive protection already there for everything else, and protected from getting bent/damaged while it's protecting the motor and drivetrain.

I'm glad you posted this, I'm a senior in highschool and have already been accepted into some colleges to study mechanical engineering. I'm hoping to continue on to getting a masters in robotics engineering, but I don't want to wait that long to get into combat robotics. I don't have any previous experience with CAD or basically any machines other than bandsaws, though I do know a bit about arduino. I'm looking into making some rc bots for practice but I'm not sure if I'll be able to do that before I get into college.
